Bruno: sovereignty score and 8 European alternatives

Bruno is an open-source API client for exploring and testing APIs, positioned as a lightweight alternative to Postman and Insomnia. Collections are stored as plain-text files in a folder on your own filesystem, so you can version, compare and share them with your team using Git. Bruno runs as a desktop application on macOS, Windows and Linux; a command-line version is available through npm and as Docker images. Most features are free, and paid versions also exist, including enterprise features such as SSO/SAML and SCIM.

According to the project, Bruno is local-first: it has no cloud sync and needs no account or login, and your data never leaves your machine. The source code is available under the MIT licence on GitHub. For a European organisation this means API definitions and test data stay under your own control, inside your own Git environment. The Bruno name is a trademark held by Anoop M D.

Why digital sovereignty matters with Bruno

Bruno is headquartered in IN, outside the EU. Contracts and data therefore also fall under non-European law. The GDPR applies through contractual terms, but in a conflict with local legislation you have less certainty than with a European vendor.

Bruno hosts data outside the EU (self-host). Personal data therefore leaves the EU, which requires a transfer mechanism under the GDPR and pulls the data residency score down.

Bruno is open source. You can audit the source code, self-host the software and keep the encryption keys under your own control. Switching is easier because data and software are not tied to a single party.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Bruno together with your other vendors and gives a total score, a heatmap and the main risk drivers.
